  • the device 12 may contain a serial number or expiration date, and may be traceable, for example, to determine whether or not a drug is under recall.
  • the device 12 may also be used to confirm that the medical component 10 is an official product, rather than a third party grey market copy or other counterfeit.
  • the device 12 may also be used, for example, by an RFID check to ensure that the medical component 10 is an appropriate delivery device for the drug to be dispensed.
  • the device 12 may also be used to control the dispensing of the drug from the medical component 10 and to update inventory levels automatically.
  • the electronic device or package 12, according to any of the embodiments described herein, may also incorporate measurement technology, such as for measuring or detecting the location of a piston during use and/or the speed of delivery of the drug (e.g., by monitoring the piston rate of movement), or for providing feedback about when a piston reaches a pre-set dosage point (for example, the device 12 may be used to drive haptic feedback in the medical component 10).
  • the electronic device 12 may be used to determine when the replacement should occur or if drug exposure should be limited.
  • the electronic device 12 may also be used to detect tampering.
  • the device 12 may include a resistive foil whose value changes if it is punctured by a needle.
  • the electronic device or package 12, according to any of the embodiments described herein, may also incorporate various other types of technology.
  • the device 12 may incorporate muscle wire (flexinol or Shape Memory Actuator Wire) technology in the shape of a coil inside the rubber medical component 10 coupled to the electronic device 12. When a current flows throw the muscle wire, the muscle wire contracts. Such functionality could be used, for example, to tense/relax the piston 10, in order to make it easier or more difficult to move.
  • the device 12 may also incorporate piezo technology (including, but not limited to, PVDF which is a piezeoelectric material or a piezoelectric device) to agitate the drug contained in the medical component 10 prior to use.
  • Another possible use of the electronic device 12 is to actuate induction heating to heat the drug contained in the medical component 10 prior to use, or to effect intentional spoiling of the drug if a tampering or misuse alarm is triggered or if a patient is attempting to dispense the drug after its expiration date.
  • the electronic device 12 may also enable electrical contact between the piston 10 and the actuating rod to supply power to the piston electronics and confirm if the drug contained in the medical device is correct, monitor the date, etc.
  • the present invention may also be implemented to encapsulate other materials, besides an electronic device 12, inside of the medical component 10.
  • any of the methods described herein may be used to encapsulate or embed an incompressible material in the elastomeric body of the medical component 10 to change the mechanical properties of the medical component 10.
  • any of the methods described herein may be used to encapsulate or embed a dense material in the elastomeric body of the medical component 10 to change the weight of the medical component 10, for example, for purposes of gravity or acceleration induced operation of the medical component 10.
  • any of the methods described herein may be used to encapsulate or embed a magnet or a magnetic material in the elastomeric body of the medical component 10, such that the magnet or magnetic material is configured to interact with external sensors or magnetic packaging.
